Alomost sure my 04 Gt is a lemon. Had it in now 4 or more times for this nasty vibration at 1100 r.p.m and it has been in for a tranny rebuild thanks to the t3650 t.s.b. I am most likly going to go for an 03-04 cobra with under 20K on it. Had a few questions,what do I look out for in a cobra meaning is their anything I should positivly check for before purchasing? Heard some of them had a piston to cylinder wall clearance issues. Please all Cobra input is appreciated thank you Jones out
